Well, this would be a good time to post the output of "postconf -n",
"postconf -Mf" (assuming sufficiently recent version of Postfix, else
the master.cf pruned of comment lines) and any pertinent transport table
entries.
Also output from prior delivery attempts for the message in question, those may
have tried IPv4. When both are enabled, the choice of which to prefer is
random.
If you don't have IPv6 connectivity, you really should disable IPv6 (by setting
inet_protocols=ipv4). So just because the last delivery fails with IPv6, does
not mean that IPv4 was never tried.
